   What is radiation and how are people exposed to it?

   • Radiation is the emission of energy as electromagnetic waves or moving subatomic particles. Natural radiation comes from many naturally occurring radioactive materials found in soil, water, air and in the body. Every day, people inhale and ingest forms of radiation from air, food and water.

   Can radiation cause cancer?

   • We know that radiation at high doses can cause cancer and even lead to death. How radiation is delivered affects health impact. A dose received over a period of time is less harmful than the same dose received quickly at once. Radiation exposure to one part of the body is less harmful than a dose to the whole body.
